The Eaton (Hopewell) Furnace was erected in 1802 and operated between 1803 and circa 1808 when, due to a combination of factors, it went out of blast. Three summers of excavations and the post-season analysis of the artifacts and raw materials helped to piece together the activities taking place at the site and to evaluate the efficiency of the ironmaking operation. The findings indicate that a new chapter will have to be written on Ironmaking in the New World. -- AATA
